Chirally self-assembled porphyrin nanowires assisted by L-glutamide-derived lipid for excitation energy transfer.

An L-glutamide-functionalized tetraphenylporphyrin () has been newly synthesized and its self-assembling behavior in organic solvents is reported. forms nanofibrous assemblies in a dilute solution to show specific induced circular dichroism at the absorption band around the porphyrin moiety. It enables us to observe the meso-stable and stepwise H- and J-like hierarchical aggregations. Energy transfer studies in a mixed system with a pyrene-functionalized L-glutamide reveal the promotion of energy transfer from the pyrene excimer to the porphyrin moiety.
